The PSNI has made an arrest after the report of "a male tampering with numerous life rings". This is reported to have happened in the early hours of Monday, March 17 on the Craigavon Bridge.
It's reported the male was "opening their housing" and 'threw one into the River Foyle'.
Police Derry City & Strabane added: "There was no reason for him to do so. Police quickly identified and apprehended this male, arresting him for public order offences. He was conveyed to Custody and will be processed accordingly.

"Within minutes of this call, Police received a report from the public concerned for a different person on the Craigavon Bridge which we also dealt with.
"The contrast between these two calls could not be more stark and the consequences unthinkable, especially if the life ring was needed and not available due to someone else’s inconsideration.
"The life rings are there for a reason, a reason many people in this city sadly have personal experience of. It is for this reason that Police take a zero tolerance approach to any tampering or damage caused to them.
"If you see anyone interfering with the life ring equipment please call Police on 999 as these are key lifesaving tools and may be required at any time."
